Overview
The BL741-T3 is a universal and miniaturized gas detection module. It is equipped with a fuel cell-type electrochemical button sensor, which not only features low power consumption but also effectively avoids the risk of liquid leakage that is common in traditional electrochemical sensors. In terms of the circuit, it adopts an instrumentation amplifier, a high-precision AD converter, and other components to convert the detected gas concentration into digital signals. Data transmission can be carried out through signals such as serial ports and PWM, ensuring stable signals and providing multiple options.
Key Features
- High temperature resistance and fast response
- Low power consumption and high precision
- Long service life and working abnormality prompt
Applications
- Vehicle lithium battery failure detection
- Hydrogen gas detection in energy storage power stations
- Portable hydrogen gas detectors, etc.
